  • Arsenic biotransference to alfalfa (Medicago sativa)

    The arsenic (As) concentration in the edible part of crops depends on the availability of the As present in the soil and the ability of a crop to take up As and translocate it to the target organs. The aim of this study was the determination of As concentration in soils and alfalfa (Medicago sativa) in field conditions and pot experiments to analyse As soil–forage transference. Results show that ...

  • Leachate and Hydrolysate Content of Food Grade Polymers using Microwave Preparation with Non-Contact Temperature & Pressure Control

    Food SAFETY is a primary concern for manufacturers and consumers World-wide. While there is always concern for the Food PRODUCT itself… from either Microbial or Chemical contamination… there is also a need to preserve Food for storage and shipment, and the desire to minimize packaging waste, and many Food items are sold as “ready-to-eat” products. Now we must concern ourselves with the ...

  • Bioaccumulation of Heavy Metals, Organochlorine Pesticides, and Detoxication Biochemical Indexes in Tissues of Ictalurus melas of Lake Trasimeno

    Organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs) and heavy metals are persistent substances ubiquitously present in aquatic ecosystems. Their bioaccumulation in biota is governed by the physico-chemical properties of the compounds, the bioavailability from environmental matrices, the structure of the food chain, the lipid content of the species and the metabolism of the exposed ...

  • Using Solid Phase Extraction for Determination of Contaminants in Water

    Pesticides, Polychlorinated Biphenyls (PCBs), andpharmaceuticalsare a worldwide contamination problem. Because these contaminates are long lived in the environment and bioaccumulate throughout the food chain a great deal of research and regulations has been implemented. Several major US water bodies such as the Hudson River, St. Lawrence River, Fox River and the Great Lakes have been contaminated ...

  • Treatment wetlands in decentralised approaches for linking sanitation to energy and food security

    Treatment wetlands (TWs) are engineered systems that mimic the processes in natural wetlands with the purpose of treating contaminated water. Being a simple and robust technology, TWs are applied worldwide to treat various types of water. Besides treated water for reuse, TWs can be used in resources-oriented sanitation systems for recovering nutrients and carbon, as well as for growing biomass ...

  • Water-based diseases

    Waterborne diseases are caused by pathogenic microorganisms which are directly transmitted when contaminated fresh water is consumed. Contaminated fresh water, used in the preparation of food, can be the source of foodborne disease through consumption of the same microorganisms. According to the World Health Organization, diarrheal disease accounts for an estimated 4.1% of the total DALY ...

  • Photocatalytic and adsorption studies on the removal of dye Congo red from wastewater

    Many industries such as paper, food, cosmetics, textiles etc. use dye in order to colour their products. The presence of these dyes in water even at very low concentration is highly visible and undesirable. Colour is the first contaminant to be recognised. Photocatalytic technique and adsorption methods offer a good potential to remove colour from wastewater. In the present paper these two ...

  • High Throughput LC-MS-MS Analysis of Carbendazim in Orange Juice

    Highly sensitive analytical methods are necessary to prevent contaminated produce from entering the food supply. In order to help move fresh imports through customs without delay, methods must be rapid and cost effective, in order to test imports thoroughly. LC-MS offers the highly sensitive, robust measurement needed, while ultra high performance liquid chromatography enables high speed ...

  • Legal Lookout: Mercury Rising

    Mercury is a potent toxin that accumulates in the food chain. Emissions come from both natural and human-generated sources. The mercury content in coal, which is released when the fossil fuel is burned, contributes the single largest percentage source of humangenerated mercury emissions in the United States. According to EPA, total global emissions from all sources, both human-generated and ...

  • Role of irradiation treatment in the food industry

    Irradiation from radioactive elements, such as cobalt-60, or an electron beam, can be applied to raw materials to prevent the proliferation of plagues or to kill bacteria that could be present in ready-to-eat foods or industrialised ingredients. It is therefore an important tool in food safety and food security. Food contamination by some pathogenic bacteria, such as Salmonella sp. or Escherichia ...

  • Odour control with Direct Cold Plasma

    Odour emission during the production or processing of food and feed is often an unwelcome side effect. However, by using cold plasma technology, the smell can be reduced up to 95%. Increasingly, feed manufacturers are being required to address the issue of emitting of odour and harmful contaminants into the surrounding community. Local communities, special interest groups and government ...

  • Comparison of probabilistic approaches to estimate the initial bacterial levels as a start in exposure assessment: Escherichia coli O157:H7 in beef as an example

    The initial contamination of food products with pathogens is an important risk factor in microbial risk assessments. This factor contains variability and uncertainty that can be calculated from various available monitoring results. When performing dedicated quantitative risk assessments, different methods can be chosen to transform the data into probability distribution functions. This paper ...

  • EPS Food Containers Can be Recycled

    EPS food containers can be recycled. In our daily life, we can see vast majority of EPS food-service products are used in commercial districts. However, there is no collection of EPS for recycling, as EPS food containers are typically not “clean” enough to be recycled. Plus, the high costs of collecting, sorting, and transporting this big volume EPS make the ...

  • Microbiological quality of ice and ice machines used in food establishments

    The ice used in the food industry has to be safe and the water used in ice production should have the quality of drinking water. The consumption of contaminated ice directly or indirectly may be a vehicle for transmission of pathogenic bacteria to humans producing outbreaks of gastrointestinal diseases. The objective of this study was to monitor the microbiological quality of ice, the water ...

  • Concentrations of heavy metals in plants grown on polluted mining soils (Loma Charra mine, Spain)

    Evaluation of heavy metal accumulation in plants is of environmental importance due to its toxicity effects in humans and other biota. Soils and plants were sampled in a polluted site around a Pb-Zn(Cd) mine. Total metal contents in the soil indicate a gross degree of pollution in relation to background levels. Soil Cd shows high mobility and availability and consequent high environmental risk. ...
